Double Square Inch (abbreviations: in4, or in 4): is a unit in the (British) imperial and United States customary systems of measurement of area moment of inertia, a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.
Double Square Centimeter (abbreviations: cm4, or cm 4): is the SI derived unit of area moment of inertia, a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.
How to Convert Double Square Inches to Double Square Centimeters
Example: How many double square centimeters are equivalent to 29.81 double square inches?
As;
1 double square inches = 41.62314256 double square centimeters
29.81 double square inches = Y double square centimeters
Assuming Y is the answer, and by criss-cross principle;
Y equals 29.81 times 41.62314256 over 1
(i.e.) Y = 29.81 * 41.62314256 / 1 = 1240.7858797136 double square centimeters
Answer is: 1240.7858797136 double square centimeters are equivalent to 29.81 double square inches.
